Pocket-lamp.

Application filed ld, 2.9M. Ecrial lio. @lli-E14 To all whom t 'may concern', y y l -lle it known that I, @SCAR ih'loiiiriu, a cmi'iposed of opal ass and transparent citizen of the United States, residingat New York city, county and State of New Yorli,

have invented e. new and Improved Pocket? Lamp, of which the following is a speci ication.

This invention relates to an electric lamp of novel construction which permits ,a ready exchange of the light bulb and battory, emits a maximum amount of light forl the electric current consumed, While its 'conf stituent parts are. so arranged thatj'tney occupy but a minimum space. v y y The invention further comprises other novel features of construction as more fully brought out in the appended specification and claims.

ln the accompanying drawing: Figure l is a vertical section through. a pocket lamp embodying my invention; Fig. 2 a transverse sectionon line 2-2 Fig. l; Fig. 3 a top vien' 'or' the lamp with the lid opened; Fig. d a section on line f l, Fig. l, with the battery omitted` and Fig. 5 cross section through the light bulb.

T he casing A of my improved pocket lamp comprises essentially a. pair of parallel i'lat sides l0, rounded ends ll, and an integral bottom l2. Casing A is adapted to accommodate a similarly shaped dry cell or battery 13, that rests en bottom l2, while the casing extends upwardly beyond battery 13, to here form a compartment lli for the reception of the light bulb l5 and the contact springs 1G, l? of the battery. To one ot the dat sides l() of casing is hinged at lil a lid 19 which is provided with a springy ng. To the inner face of lid 19 is soldered or otherwise connected a spring clamp 22 for the engagement with the socket 23 of bulb l5, theclamp 22 being so disposed relatively to the lid that bulb 15 lies flat against the latter, e. that the longitudinal bulb axis in parallelism to tue erred to use glass tubing that is partly l i glass, both kinds or glass being united along dienie'trieally opposed4 lines 29- Wliich occupy a common plane with that of lainent 24 as in ."'cated in 5.

. :iemay here be stew' that with the pocket lamps hitherto generally used, the longitudinal aries of the light bulbs extend at right angles to the plane of the lamp tops, said arrangement requiring the use of tipless bulbs, the manufacture of which is more expensive than that oi bulbs having the usuel end tips. is with my construction the eide or the bulb only, is exposed through ,opening 25s the bulb may have an end tip 30 so that the cost of' the pocket lamp is correspi. ingly reduced. is furthermore upri bulbs occupy more space above cell 13 23 than is required lor my bulb which extends -id 19, the longitudinal dimension of the er g is considerably re duced. which reduction in length is en.- treinely important with lamps designed to be carried in the pocket.

ln order to permit ready removal of cell 13 througl'i the opened top oi casing fi. Without iiu'cererineq with the movable stud 31 for lighting the bulba the .following construction lias been devised:

One ot the rounded ends ll of casing A is provided with a longitudinal enlargement or pocket 32, to the inner side of which is riveted or otherwise secured the lower end iiat spring carrying a push button at proiects outward through e correonding aperture ot said enlargement. l proximity to the upper end of 3, there is secured thereto an inwardly ex ending eye 3G into which is removably l a resilientbar 37 accommodated Withn pocket 32 and carrying near its inwardly eilected upper end 38, the stud 31 hereinabove referred to. lt will be seen that by pressing button 34, the latter transfers its movement through spring 33 and bar 37 to stud 3l, thereby effecting an engagement between the latter and contact 17 and thus closing the bulb circuit. lf al worn cell 13 is to be replaced by a fresh cell, lid i9 is opened and the casing A is turned upside down so that the cell will slide outvarrl,l thereby taking along bar 37 owing to the. 'ement o? cell stud After Les b "i introduced, bar 3'? 33 uns.u occupies si iet tion shown in Fig. 1 whereupon lid '19"is',

closed and the lamp i's again readyf6r"u'se. Ielaim: w 1. Apocket-lamp comprising a casing'` a cell inclosed thereby, an apertured lid adapted to close the casing,a light bulbfre- .movbly secured tothe 11d and exposed through the lid aperture, the lon tudinal axis of the bulb extending in su stantial ductively` connecting the cell bulb. 2. pocket lamp comprising a casing. a

, parallelism With'the lid, and means for oo ncellinclosed thereby, .an apertured lid` adapted to closethe casing, a spring clamp on? the lid, a light bulb removably engaging said clamp and exposed through the liolap erture, the longitudinal axis ofthe bulb extending insubstantiagl :parallelism with the lid, and Ameans for conductiyely connecting the cell and bulb.

3. A pocket lain 'comprising a casing, a

4cell in'closed there y, anjapertured flat lift vhinged to the'casing, as springclamp on the lid, alight bulb removably engaging said clanipandexposedthrough the l1dapertur e,' the longitudinal axis of the bulb extending in substantial parallelism with the lid, an d means for conductively connecting `the cell vand bulb.

fl. A pocketl lamp comprisinga casing, a

cell'inclosed thereby, an apertured lid parent glass portion that is exposed through the lid aperture the longitudinal axis of the `bulb extending in parallelism to the lid, and

that is adapted to engage the cell-contact.

6. In a pocket'lainp, a casing having rounded ends, a pocket formed at oneof said ends, a cell inclosed Within the casing and having a Contact, a spring secured to the inner side of said pocket, Ial push button and an eye carried by vsaid spring, a resilient vbar removably` engaging 'the eye and received Within the pocket, and a stud on said bai-.that is adapted to engage the cellcontaet.
